Sony Xperia Z1 C6903 (Honami) can now be updated to Android 5.0.2 Lollipop OS using AOSP custom ROM compiled directly from Sony’s open-sourced Lollipop build by FreeXperia Project (aka FXP).

It is totally crammed with bugs and is only meant to give you an early glimpse of Lollipop running on your machine. We’ve given the necessary download links and a handy tutorial on flashing this firmware in this article below.
